EXAMPLE 3:
Variable value= REFERENCE, range= Min ref - Max ref
Range needed for output= Min ref (0%) - Max ref (100%), 0-10 mA
Output signal 0 or 4 mA is needed at Min ref - set par. 6-51
to 0%
Output signal 10 mA is needed at Max ref (100% of range) - set par. 6-52
to 200%
(20 mA / 10 mA x 100%=200%).
